BACKGROUND OF THE INVENTION

The present invention relates generally to a solar ventilator and aventilating system with the solar ventilator, and more particularly toan innovative one which permits to convert the available solar energyinto electric energy required for the ventilator in the daytime, andalso store the converted electric energy into the energy storage unit toprovide power required for the ventilator in the nighttime; the solarventilator can be applied to the external surface or interlayer of thebuilding roof so as to form the building's ventilating system.

With the growing awareness of environmental protection and energysaving, a high priority of technological development must be placed onenvironmental protection and energy conservation to meet theenergy-depleting challenges in the future. Thus, the key concern ofresearch and development is to develop new energy sources or convert andutilize the energy sources in the nature or recycle the energy sources.Given the highest availability of solar energy in the nature, thetechnology of converting solar energy into electric energy is becomingmore mature, and also commonly used to provide electric source for thepeople's everyday life. To save power of the factories or workshops witha bigger power consumption, several ventilators are generally arrangedon the roofs of such industrial buildings. However, such sphericalventilators are protruded from the surface of roof, and rotated underthe drive of air convection to pump out the indoor hot air; but, theprotruding of spherical ventilators from the roof surface is notaesthetically pleasing, and the natural convection method for drivingthe rotation of ventilator blade and pumping out hot air cannot bringabout good result. For this reason, power supply is adopted to drive theventilator for forced air convection and pumping, leading to increase ofpower consumption and operating cost; some improvements are thus made toinstall a solar panel, which converts the absorbed solar energy intoelectric energy required for the ventilator, thus reducing greatly thepower consumption in the daytime. However, many industrial workshops arerunning around the clock, so the ventilating system must be operated dayand night, and indoor power supply shall be provided for the ventilatorin the nighttime to resolve the problem in this regard.

Thus, to overcome the aforementioned problems of the prior art, it wouldbe an advancement if the art to provide an improved structure that cansignificantly improve the efficacy.
